APPARATUS FOR COOLING, DISINFECTING, PERFUMING,&.C.

SPECIFICATION forming part of Letters Patent N0. 235,960, dated December28, 1880, Application filed May 20, 1880. (F model.)

To all whom it may concern:

Be it known that I, GEORG PRAETORIUS, of Breslau, Province of Silesia,Kingdom of Prussia, Empire of Germany, have invented certain new anduseful Improvements in Devices for Filtering, Cooling, and SimilarPurposes, of which the following is a specification, reference being hadto the accompanying drawings.

Figure 1 of said drawings represents a side elevation of a jar forcooling and moistening tobacco. Fig. 2 represents a vertical sectionthrough the same. Fig. 3 represents another vertical section of the sameon the lines a; m of Fig. l and y y of Fig. 2. Fig. 4 represents Fig. 5represents a horizontal section through the latter. Fig. 6 represents avertical section of another modification. Figs. 7 and 8 representvertical sections through two dishes or receptacles for containing andcooling butter or other substances. Fig. 9 represents an iceholder orrefrigerator in vertical section. Fig. 10 represents a vertical sectionof an evaporating apparatus. Figs. 11 to represent different forms ofwater-closets and chambers, in vertical section, embodying my invention.

In all the devices hereinbefore referred to a portion is glazed orotherwise made imper vious to water, while certain other portions areleft un glazed or porous. The un glazed portions are indicated by dottedlines.

In Figs. 1 and 2, A designates the cover; B, the hollow body of thevessel; (1, the hollow base of the latter, and D the hollow handle ofsaid vessel or jar. All parts are preferably made of earthenware. Thebase 0 is separated from the body B by a horizontal partition, 0, ofunglazed earthenware. There is also an annular unglazed part, F, in theupper part of the material composing the body B. The remainder of thejaris glazed within and without, except the walls of hollow base O. Theupper part of arm D has an inlet,

which is closed by a stopper, E. Hollow base 0 is provided with anair-outlet, G. The tobacco is placed within body B, and water is thensupplied through handle D to base 0. This water percolates up throughpartition 0, and after moistening the tobacco evaporates throughunglazed annular part F. This evaporation cools the tobacco.

Fig. 3 shows a hollow body, B, for receiving the tobacco, and a hollowcover, A, for containing water. This cover has an unglazed bottom, 0,through which moisture passes to Fig. 7 shows a butter-dish, B, having adetachable cover, A, a hollow base, 0, and hollow arms D, communicatingwith the interior of said base. One of these arms is provided with anopening, 0, for supplying water, and

the bottom of butter-dish B is left unglazed, so as to allow the waterto rise and cool the butter. The handles D are left unglazed tofacilitate evaporation.

Fig. 8 shows a similar construction, except that the cover is perforatedand partly unglazed, it also being shaped so as to take the place of thesides of the dish. The base is hollow and saucer-shaped, and providedwith two concentric annular flanges, between which the cover sits. Theouter flange has an inletpassage communicating with the hollow of saidbase for the supply of water.

In Fig. 10, S indicates a cup or saucer for holding articles which areto be subjected to the action of vapors in chamber A. G designates ahollow porous base supporting the same, and adapted to be supplied withliquid through inlet R. E F designate vaporizingplates suspended fromthe cover D. A hollow space, B, below G, may receive additionalmaterial, such as sulphuric acid. Such additional material may act as anabsorbent of vapor or as a generator of vapor.

In Fig. 17 a chamber-pot is shown constructed after the manner of thereceptacle in Figs. 1 and 2. The hollow base B may be supplied withdisinfecting-fluid through the handle, and this fluid will rise into thechamber through the unglazed bottom thereof. Vapors will pass offthrough unglazed part F when the cover is on.

ICO

them, forming a permanent part of the said vessel, as set forth.

In testimony thereof I have signed this specification in the presence oftwo subscribing witnesses.
